Unit 1: Day 5
Daily Objective: Similar Figure: What are they and finding missing length.
Definition: Similar figures are figures that have the same shape but not necessarily the same size. To find the missing lengths you have to make ratios with the corresponding lengths of the two figures. Once you have the ratios, you have to then cross multiply and then divide.
Pictures: This shows a good example of how you need to make ratios with the corresponding lengths and then multiply and divide.
3 question quiz:
#1. What would be the missing length of a figure that has a width of 4 and a missing length, (x), and another similar figure that has a length of 6 and a width of 9?
#2. What would be the missing length of a figure that has a length of 8 and a missing width, (x), and another similar figure that has a length of 2 and a width of 4?
#3. What would be the missing width of a figure that has a length of 5 and a missing width, (x), and another similar figure that has a length of 10 and a width of 5?
Answer key:
#1.
#1.
#2.
#3.
